Production Season 4 was the fourth and last season of the first run of Futurama. It consisted of 18 episodes, and ended with what became a 'series finale'. It was not until 23 March, 2008, that a new episode of Futurama would air on television again.

The people at FOX Network told the writers and producers that this season might be the last thing they were ever going to do. But there was a 50-50 chance that the show might get picked up again. The writers, specifically Ken Keeler, wrote the season finale, which turned out later to be the series finale, as a closure episode, but without wrapping everything up.
